On CAPS, 26% of the 1,145 members who have rated Lululemon believe the stock will underperform the S&P 500 going forward. These bears include All-Star kurtdabear, who is ranked in the top 15% of our community, and Jeffrey2012.

Earlier this summer, kurtdabear touched on Lululemon's seemingly unsustainable stock price: "This little rocket stock looks like it's perilously close to maximum altitude. While I generally don't bet against debt-free companies, LULU has a price like a high-tech phenomenon and will probably have difficulty growing going forward in an atmosphere of consumer retrenchment."

In fact, lululemon currently sports a lofty forward P/E of 40.5. That represents a clear premium to competitors like Gap (9.4), Nike (14.7), and Under Armour (29.9).

This is actually a really good business since they have managed to sell out their products at [full price] without markdowns. Very few retailers can actually do that.

That said, way too many investors have been eyeing any ounce of growth and thus pounced on LULU. While it is quite possible they may very well continue to outperform in terms of their business, the stock has run way too far ahead of fundamentals. Not only that, but there is no doubt they will continue to face selling pressure going forward because fund managers who needed to sell their winners will definitely be looking at LULU.
